WINDOW CONSTRUCTION.

Application led November 1, 1920. Serial No. 421,023.

To all whom t may concern.'

Be it known that I, ARTHUR R. MITCHELL,

a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of IVisconsin, have invented new and useful Improvements in Window vConstruction, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

i This invention relates to certain new and useful improvements in window construction and refers more particularly to one in which the sash is permitted a swinging movement from the vertical for convenience in washing the windows and Ventilating. 1

Another object of this invention is to provide a window construction in which the sash is permitted a swinging movement from the vertical and which has means .whereby an air tight joint will be formed between the sides of the sash when in vertical position, which means also serve to retain the sash at any angle.

Another object of this invention is to provide a window construction of the class described including side runners to which the sash is pivotally connected and having antirattling means for urging the ends of the runners to snug engagement with the sides of the sash when in vertical position, and

having means for permitting the passage upwardly of the usual sashv cord.

Afurther object of this invention is to provide a swinging sash havingy carrying runners provided with weather strips formed Y integral therewith for making an air-tight but sliding` connection with the window frame.

A still further object of this invention is to provide a window construction of the class described which will be of simple construction, of a neat and/attractive appearance, and capableof production at a comparatively low cost.

With the abo-ve and other objects in view which will appear as the description proceeds, my invention resides in the novel construction,'combination and arrangementof parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawings, I have illustrated one complete example of the physical embodimentvof my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a vertical sectional view showlng a double hung window constructed according to my invention, both sashes being shown in position swung out of the vertical;

Figure 2 is a view on an enlarged scale of but one sash, parts thereof being broken away and parts being shown in section to more; clearly illustrate various structural details;

Figure 3 is a transverse sectional view on an enlarged scale taken on the line 3- 3 of Figure 2; and

Figure 4 is a sectional view on an enlarged scale taken on the plane indicated by the line 4 4 of Figure 3, said View having parts broken away.

Referring now more particularly to the accompanying drawings, in which like numerals designate like parts throughout the several views: n

The numeral 5 designates the jambs, 6, the head and 22, the sill of an ordinary window. In the drawings, these pieces are illustrated as constructed of wood, but, as will be readily obvious, these parts may be constructed of metal or any other suitable material. The window frame just described is provided with the ordinary stops 7 and part ing strip 8. Arranged for movement longitudinally ofthe jambs between the stops and parting strip are sash runners or plates 9, preferably constructed oftrough-shaped metallic strips Yhaving'their ends lled with reenforcing blocks 10 and their outer faces corrugated to provide longitudinally extending parallel ribs 11.

Pivotally swung between thev runners 9, in the manner hereinafter described, is a sash 12 of any construction and having alined depressions or recesses 13 formed'in the stiles thereof. Carried. by each stile is a metallic plate 14 which is provided with inwardly struck longitudinally extending parallel ribs 15 to conform with the face of the adjacent runner 9. The two plates on each side of the sash, i. e. the plate 14 secured to the sash and the plate 9 adjacent the jamb, forms a tortuo-us path, when the sash is in the vertical position, which effectually excludes air and weather.

The sash 12 is pivotally connectedrwit'lr the two adjacent runners 9 by pivotl bolts 16 which have their heads disposed within the depressions 13 and )assed through alined apertures within the plates 14 and runners 9. Positioned in each depression 13 is a leaf spring` 17 through the center of which the pivot bolt 16 passes. Each spring 17 has its central portion enclosed by a shield 1S of substantially U-shape in cross section and the springs 17 tend to draw the pivot bolts 16 into the depressions to retain their securing nuts 19 snug against the inner faces of the runners 9. This construction tends to yieldingly retain the runners 9 in snug engagement with the plates 14.

Secured on each pivot bolt 16 between the inner face of the runner 9 and the securing nut 19 is a hook member 2O over which the lower end of a sash cord 21 is engaged, the sash cord being passed upwardly in the adjacent runner and outwardly through a central groove 22 in the top end block 10 thereof.

By reason of the sash and runner being held together by the springs 17, it is obvious that there will be no rattling or relative movements of these two parts, but in order to prevent rattling between the runners and the jambs and to insure the snug engagement between the extreme ends of the runners and plates 14, I employ the anti-rattling devices, positioned adjacent the ends of each runner 9 and concealed therein.

Each anti-rattling device comprises a pair of spaced arms 23 having their inner ends `iournaled on pins 24 carried by the sides of the runner and having their outer ends connected together by a rod 25. Mounted on the rod 25 between the arms 23 is a roller member having a reduced medial portion 26 and enlarged bearing end portions 27. This construction permits the free upward movement of the sash cord 21 between the roller member and the window jamb as will be readily apparent. Connecting the arms 23. intermedia-te the ends thereof, is a second rod 2S with which the ends 29 of a substantially U-shaped spring member engages.

This spring member has the sides of the U thereof coiled about cap members 30 carried by the inner ends of the arms 23 and engaged with the pins 24, then extended upwardly and has the base 31 of the U pressing against the runner 9, see Figures 2 and 3.

With this construction, the ends 29 press outwardly against the rod 28 and the base portion 31 presses inwardly against the runner 9 to 'thus yieldingly urge the roller member against the jamb to retain the same snug.

As before stated, one anti-rattling device,

as described, is positioned adjacent each end of the runners 9 and thus a pressure is at all times exerted at each end of the runners to prevent the rattling thereof without interference with the free sliding movement of the same in the j amb.

In order to insure against the air or weather passing between the runners and the j amb, the inner sides of the lower portion of the parting strip 8 is provided with a metal strip 32 and the upper outer' portion thereof is also provided with a similar strip 32, which strips have a snug but sliding engagement within guideways 33 formed inthe adjacent sides of the runners. The guideways are formed by extending one side of each runner beyond the other, then folding the same back snug against the runner, then folding the same aga-in outwardly to provide the space therebetween, as clearly shown in Figure 3. This construction provides protection against the air or weather' passing between the runner and the window jamb and may be added to the window without materially increasing the cost thereof.

Tt is obvious from this construction, that the windows may be swung to any desired angle, or either window sash may be raised and lowered with its respective runners to any desired height. By reason of the pivotal connections described, the plates 14 carried by the sash bear against the runnin rails 9 with sufficient friction to hold the sash in any desired angle as required for Ventilating the room or washing or painting of the windows.

It is obvious from the construction shown and described that when the windows are in a closed position, the double beaded plates 14 secured to the sash and the double beaded sash runners 9 form a weather tight connection between the sash and runners.l the combined weather strips carried by the vrunners and parting strips form a weather tight connection between the runners and the window frame, and the anti-rattlers in addition to preventing rattling of therunners relative to the jamb also serve to hold the runners tightly against the sashes.

What I claim as my invention is:

1. In combination a window frame having vertically extending guideways, a sash frame, runners associated with said frame and adapted to slide in said guideways, a sash cord in one of said guideways fixed to and arranged to support said sash frame, and an anti-rattler device associated with said sash frame including a roller adapted to travel in the guideway in which said sash cord is located, said roller being grooved to permit the passage of the sash cord between it and the opposite wall of the respective guideway without interference.

2. Tn combination a window frame having vertically extending guideways, a sash frame, runners associated with said frame and adapted to slide in said guidewa s, sash cords in said respective guideways Xed to and arranged to support said sash frame.l and anti-rattler devices associated with the respective vertical edges of said sash frame, each of said devices including a springpressed arm pivoted at one end to its respective one of said runners and having a roller 10 journaled on the other end adapted to travel in the adjacent guideway, said roller being grooved to permit free passage of the sash cord between it and the opposite Wall of the respective guideWay.

In testimony whereof, I aiiix my signature.

ARTHUR R. MITCHELL.
